Let's divide 91188297 by 51
We're looking to find how many times 51 goes into 91188297.

On to step 1:
When dividing 9 by 51, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 51

On to step 2:
51 can be fit into 91 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 40 after subtracting 51 from 91.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 51

Moving on to step 3:
401 divided by 51 is 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 357 away from 401, we end up with 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 51

Moving on to step 4:
51 goes into 448 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
If we subtract 408 from 448, we get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 51

Moving on to step 5:
51 goes into 408 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1788.0
If we take 408 away from 408, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 51

Moving on to step 6:
When dividing 2 by 51, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 17880.0
If we subtract 0 from 2, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 51

Advancing to step 7:
If we divide 29 by 51, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 178800.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 51

Advancing to step 8:
51 can be fit into 297 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 1788005.0
Subtract 255 from 297 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1788005.8
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
When dividing 120 by 51, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1788005.82
Subtract 102 from 120 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
If we divide 180 by 51, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 1788005.823
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
51 goes into 270 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1788005.8235
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
When dividing 150 by 51, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1788005.82352
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
480 divided by 51 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 1788005.823529
Subtracting 459 from 480 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 15:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1788005.8235294
If we subtract 204 from 210, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 16:
If we divide 60 by 51, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1788005.82352941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 1788005.82352941, with a leftover of 9e-09.
